Detailed Description

Macro Definition Documentation

ABUF_INIT

#define ABUF_INIT   {NULL, 0}

Initializer macro for an empty append buffer.

Function Documentation

abAppend()

void abAppend	(	struct abuf *	ab,
		const char *	s,
		int	len
	)

Append raw bytes to the dynamic append buffer.

Parameters

ab	Target buffer
s	String data to append
len	Length of s

Reallocates the buffer as needed and copies the requested number of bytes to the end of the buffer. The resulting buffer is not NUL-terminated; use the maintained length field ab->len.

Postcondition

On success, ab->b may be reallocated and ab->len increases by the number of appended bytes.

Note

On allocation failure, the function returns early and leaves the buffer unchanged.

abFree()

void abFree

(

struct abuf *

ab

)

Free the memory held by an append buffer.

Releases ab->b if non-NULL. Does not reset ab->len to 0.

Parameters

[in,out]

ab

Append buffer whose storage should be freed.
